我有ListView .我想单击项目并更改活动。 ListView正常工作，但是当我单击任何项目时，应用程序会停止并关闭。

ListView myListViewOfSongs;
String[] people;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    myListViewOfSongs = findViewById(R.id.songs);
    people = new String[]{
            "Mike Strong",
            "Jennifer Anniston",
            "Tom Bennet",
            "Leander Paes",
            "Liam Nesson",
            "George Clooney",
            "Barack Obama",
            "Steve Jobs",
            "Larry Page",
            "Sergey Brin",
            "Steve Wozniak"
    };
    ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,people);
    myListViewOfSongs.setAdapter(myAdapter);
    myListViewOfSongs.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            startActivity(new Intent(getApplicationContext(),PlayerActivity.class));
        }
    });
}

Answer 1

我已经检查了你的问题.您已使用getApplicationContext()启动 Intent。请替换 getApplicationContext() context

替换代码

startActivity(new Intent(getApplicationContext(),PlayerActivity.class));

自

 Intent intent = new Intent(AccountActivity.this, LoginActivity.class);
 startActivity(intent);

或

Intent intent = new Intent(this, LoginActivity.class);
 startActivity(intent);

Answer 2

启动 Intent 时不应使用 getApplicationContext((。您应该将其替换为您的活动上下文。
